STEEL FILING.

Specification of Letters Patent.

latented April 13, 1909.

Application filed .Tune 15, 1908. Serial No. 438,579.

To all 'whom it may concern:

Be it known that I, GREGOR Gnneonin- WITsCH KnrwosoHEIN, a subject oi' the Czar oi' Russia, and residing at No. 50 Spalernaja, St. Petersburg, Russia, have invented certain new and useful Improvements in Steel Filing, of which the following is a specilication.

The invention relates to steel piling to be applied in making foundations for abutments, piers, embanlnnents, docks and such like constructions.

In order that the invention may be clearly understood reference is made to the accompanying drawing and in Which:-

Figure l is a horizontal section through one form ol the invention whereas Fig. :2 is a horizontal section through a second form of the invention.

This steel-piling is composed of beams 2 which have normal I-shaped sections. The beams 2 are arranged more or less adjacent to each other, their webs being parallel one to another. Two irons 1 such as Zoresor Vauterinirons are arranged between the beams 2 backside by backside in such a Way, that the Webs of the irons I are disposed in contact one with another and the flanges of these irons 1 are in contact with the inner face of the lianges of the beams 2. The

flanges overla and engage each other to prevent latera movement. Between the diverging sides of the irons l and the webs of the beams 2 there are free spaces 3 Which can be filled with concrete thus making waterproof the steel-piling- The cross-section of the object oi' my invention is distinguished by a very great moment ol' inertia relating to line x-x surpassing the moment oi' inertia oi'l steel pilings usually composed of beams of largest cross-section.

Vv hat I claim as my invention and desire to secure by Letters atent is:

In steel-piling the combination of beams more or less adjacent to each other and having I-shaped cross-sections, with pairs oi Zores-irons inserted between each pair of said beams, the webs of said Zores-irons disposed in contact one with another, the flanges oi' said Zores-irons disposed in contact with the inner face of the langes of said beams, and concrete iilling the free space between said beams and said Zores-irons.

In Witness whereof I have hereunto set my hand in presence of two witnesses.
